How to add multiple different functions on single on submit command in javascript

Just wrap them to one function:

myform.onsubmit = (e) => { validation(e); exercise(e); } 

You can call functions inside of functions…

function myFunc() { validation(); exercise(); } <button onsubmit=“myFunc”> 

Modern javascript (by modern in this case I mean since about 2010 or even earlier) you'd use addEventListener

Like this

var myform = document.forms.hform; myform.addEventListener('submit', validation); myform.addEventListener('submit', exercise); myform.addEventListener('submit', youSaidThreeFunctions); 

You can add an event listener at any place in your code, so that's better than running the functions in another function

addEventListener is more flexible than using onEvent

let handleSubmit = (e)=>{ e.preventDefault(); // prevents default functionality of browser of reloading the webpage validation(); exercise(); // you can add more lines of code / function to be executed when onsubmit } var myform = document.getElementById("respective id of the form tag"); myform.addEventListener('submit', handleSubmit); 

Try this, you can create two individual function where each fuction is called like a stack .

function validation(){ alert(" exercise() function executed successfully!"); } function exercise()(){ alert(" exercise() function executed successfully!"); } <button type="button" onclick="sayHello();sayHi();">Click Me</button>
